How to service the spark plugs for the engine ignition systems (RH and LH, 5.4L and 6.8L) on Ford F-250 Super Duty?

The engine ignition service for the spark plugs (5.4L and 6.8L RH and LH) starts with removing the ignition coil-on-plug. No debris should exist in the spark plug space; use compressed air for cleaning before you remove them. You must reinstall used original spark plugs in their previous cylinder of removal but new spark plugs can go anywhere. The spark plugs require removal before new installation and should achieve 34 Nm (25 lb-ft) during tightness adjustments. The spark plug gap cannot be adjusted since gap adjustments will damage the ceramic surface of the spark plug. Therefore, replace the spark plug if it has an improper gap measurement. The inspection process should be followed by new spark plug installation while using the same removal method to finish the operation.
